DENSE MODE
Cisco recommends that you use ProtocolIndependent Multicast (PIM)
- Configure the global command ip
multicast-routing and the interfacecommandip pim sparse-dense-mode oneach interface that needs to processmulticast trafficor you can configure theinterface commands ip pim dense-mode andip pim sparse-mode simultaneously with theip pim sparse-dense-modecommand.

SPARSE MODE WITH
ONE RP
- Static RP configuration requires that allrouters in the PIM domain have the sameip pim rp-address commandsconfigured.
NOTE:
We can configure multiple RPs, but therecan only be one RP per specific group.
Router A is the RP which is typically theclosest router to the source

- This type of static RP configuration requires
that all routers in the PIM domain have the
same ip pim rp-addressaddress acl
commands configured.
NOTE: if we want different RPs to handle
different groups, you need to configure all
routers to include which groups the RPs will
serve
Only RP 1 or RP 2, can be the RP for all groups

- Auto-RP requires that you configure theRPs to announce their availability as RPsand mapping agents. The interface-typeoption in theip pim [vrf vrf-name]
send-rp-announce {interface-typeinterface-number or ip-address}
scope ttl-value command should containthe VLAN interface and the VLANnumber
NOTE: If you choose a physical interface,you rely on that interface to always be up
With a loopback interface, it is always upand never goes down, which ensures theRP continues to advertise itself throughany available interfaces as an RP
